PLOW.

SPECIFICATION formingpart of Letters Patent No. 711,531, dated October21, 1902.. Application led Agust 15,1902. f serial No. 119,122. (Nomodel.)

.To all whom it may oon/cern:

Be it known that 1, BEVERLY GRAY REEVES, a citizen of the UnitedStates", residing at Durango, in the county of Falls and State of Texas,have invented a new anduseful Plow, of which the following is aspecification.

This invention relates to that class of plows in which a stock orstandard is pivoted to and adj ustably connected with the beam and it'has for its object to provide an improved construction, arrangement,and combination of parts whereby the said adjustment may be effected ina convenient manner and by which the standard when adjusted may besecurely retained in position. p

My invention further consists in the improved construction ofthedetailed parts of the plow and of a drag attachment for the same, whichwill be hereinafter fully described, and particularly pointed out in theclaims.

In the accompanying drawings, Figurel is a side view of a plowconstructed in ac- Fig. 2 is a sectional View takenon the line w Fig. 1.Fig. 3 is a sectional view faken onthe line y y of Fig. l. Fig.`4is asectional view taken on the line z c' of Fig. 1. elevation.

Corresponding parts in the several figures are indicated by likecharacters of reference.

1 designates the plow-beam, the rear end of which is curvedapproximately to a semicircular shape. The foot end of the beam isprovided on opposite sides with recesses 2 2, in which are seated therearwardly-extendin g clamping-plates 3 3, the forward ends of the upperedges of which abut againstthe shoulders 4 at the upper edges of therecesses 2. The plates 3 are secured in position by means of atransverse pin 5.

Between the clamping-plates 3 3, near the rear ends thereof, is mountedthe L-shaped drag 6, which consists of a steel bar of suitabledimensions bent at right angles and having its vertical arminserted'between the clamping-plates 3, where its upper forward end restagainst a transverse pinv or rivet 7, while its rear side has a bearingagainst a clamping-bolt 8, which also extends transversely through theplates, near their lower rear corners, and which is provided with a Fig.5 is a rear nut 9,'which may be tightened so as to hold the dragsecurely in positionat any desired point of vertical adjustment. Thehandles 10 10 are also secured to the clamping-plates, upon the outersides of the latter, by means of transverse pins or bolts 11, which arearranged diagonally With relation to the pins 7 and bolt 9, thusproviding additional sup:

ports for the vertical member or shank of the drag.

The standard proper, which is designated l2, is composed'of two platesor bars 1313, which are of an elongated-S shape and'which are placed onopposite sides of the beam with which they are connected, near the pointor foot end thereof, by means of a transverse spaced at their lower endsby an interposed y block 16, through which a connecting bolt or rivet17' extends.

The parts thus far described are preferably constructed of steel.

I shall now proceed to'describe the adjusting mechanism, which is mainlyto be constructed of cast-iron.

18 designates a plate or bracket secured to the curved part of the beamand extending rearwardly from the same. The said bracket is provided onone side thereof with an annular rim or collar 19, surrounding aperforation 20which is to receive a pin or bolt 21, by means of whichthe said bracket is con-l nected with the end'of one arm of a bellcranklever 22, which said arm is provided with an opening 23, whereby it hasa pivotal i movement upon the flange 19. The other upwardly-projectingarm of the bell-crank lever is formed at its upper edge vwith a toothedsegment 24, and at its fulcrum it has an annular rim or flange 25lsurrounding a perforation 26 to receive a pin or bolt 27,`

whereby it is connected with the operatinglever 2S,Which latter has aperforation where-y by it is mounted upon the flange 25, on which it hasapivotal movement. `The lower ICO end of the lever 28 extends betweenthe plates 13 of the standard l2 at the upper end of the latter, and ithas pivotal connection with said plates by means of a pin or bolt 29.The operating-lever is provided on one side thereof with lateralprojections or brackets 30, which are perforated for the passage of anoperating-rod 31, which is provided at its lower end with a tooth 32,engaging the toothed segment of the bell-crank lever 22. The upper endof the rod 31 is bent to form a handle 33, which may be convenientlygrasped by the operator. The operating-rod 3l is also provided near itslower end with a shoulder 34 to receive the impact of a spring 35, whichis coiled upon the said rod and the upper end of which has a bearingagainst the under side of the upper projection 30.

The operation of this invention will be readily understood from theforegoing description, taken in connection with the accompanyingdrawings. By means of the op erating-lever when the tooth 32 isdisengaged from the toothed segment 24 the standard may be adjusted toany desired tilt, thus causing the plow, the blade of which is attachedin the usual manner to said standard, to run deep or shallow, as may bedesired. The standard will be locked in its operative position by thetooth 32 engaging the toothed segment 24. The drag also may be veryreadily adjusted when the bolt 9 is loosened so as to release the gripof the clamping-plates upon the shank of said drag.

The component parts of my improved plow may be manufactured of anydesired material and of any desired dimensions, and Ireserve the rightto make any changes as to the detailed construction and arrangement ofthe parts which may be resorted to without departing from the spirit ofmy invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. In a plow the combination of a beam provided at the foot thereof withrecesses having shoulders at their upper edges, rearward-extendingplates seated in said recesses and secured by transverse fasteningmeans, adrag having a shank disposed between said plates, apinconnecting the latter and forminga support for the upper front edge ofsaid shank and a clamping-bolt connecting said plates at a pointdiagonally opposite to said connecting-pin, substantially as set forth.

2. The combination of a plow-beam, clamping-plates extending rearwardlyfrom the point thereof, a drag having a shank disposed between saidplates, a pin connecting the latter and forming a support for the upperfront edge of said shank, bolts supporting the handles of the plow andextending transversely through the clamping plates and forming points ofsupport for the shank of the drag, and a bolt extending transverselythrough said clamping-plates at the heel ends thereof and provided witha clamping-nut, said bolt forming a point of support for the rear edgeof the shank of the drag, substantially as set forth.

3. The combination of a plow-beam, having recesses on opposite sides ofthe point thereof, the clamping-plates secured in said recesses, thestandard-blades having pivotal connection with the plow-beam by means ofa pin passing through the clamping-plates, a spacing-block at the lowerends of said standardplates, a bracket extending rearwardly from thebeam, a bell-crank lever having one end pivotally connected with saidbracket and having a toothed segment at its other end, anoperating-lever fulcrumed at the angle of the bell-crank lever andhaving its lower end extended between the upper ends of thestandard-plates and pivotally connected therewith, and means carried bythe operating-lever for engaging the toothed segment of the bellcranklever thereby retaining the parts at any point to which they may be adjusted, substantially as set forth.

4. The combination of a beam, a bifurcated standard having pivotalconnection therewith, a bracket secured to the beam, extendingrearwardly and having a perforation reinforced bya surrounding flan ge,a bell-crank lever, one of the arms of which has pivotal engagement withsaid reinforcing-flange and the other arm of which terminates in atoothed segment, said bell-crank leverbeing provided at the anglethereof with a transverse perforation reinforced by a surroundingflange, an operating-lever mounted pivotally upon said flange, a pivotalconnection between the lower end of the operating-lever and the upperend of the bifurcated standard,'connectin g means at the several pivotalpoints, and means carried by the operating-lever for engaging thetoothed segment of the bell-crank lever, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.

. BEVERLY GRAY REEVES.
